create_repository

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Create a new repository for the authenticated user,' which is a basic purpose statement. It does not mention side effects, permissions, or any implicit behavior like default settings or potential errors.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence with no unnecessary words. It is front-loaded with the core action and clearly states the object.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple creation tool with four scalar parameters and no annotations or output schema, the description provides just enough to understand the primary purpose. However, it lacks details about return values, failure modes, or preconditions. Given the lack of annotations and output schema, a bit more information would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75%, so most parameters already have descriptions in the schema. The tool description adds no parameter-specific meaning, but the schema sufficiently documents the parameters. The missing description for the 'description' parameter is not compensated by the tool description, but this is a minor gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'Create' with a clear resource 'new repository' and scope 'for the authenticated user'. This distinguishes it from sibling tools like fork_repository, which creates a copy of an existing repository.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It simply states what it does without mentioning use cases, exclusions, or conditions under which it should be preferred over other repository-creation tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
